In this study, the concept of drying energy was used to quantify drying performance during the drying of chili pepper and radish via a heat pump dryer with a membrane. Moreover, out of the total energy consumed during the operation of the dryer, the energy consumed for drying was analyzed by using the ratio of total energy consumed and drying energy.
The heat pump dryer with the membrane is capable of effectively removing moisture as moisture is first removed in the evaporator of the heat pump, and the remaining moisture is additionally removed in the membrane.
In the experiment, the temperature of the dryer was set to be 60℃, and the air flow rate of the dryer was changed to 49.7 CMH, 61.2 CMH, and 91.8 CMH. Based on the experimental results, the drying time was shortened by increasing the air flow rate. With respect to radish, the drying time was shortened as the width and length of the radish decreased. The drying energy utilization rate increased as the drying time increased.
Consequentially, to increase the drying performance of the dryer, the drying energy utilization rate should be increased. Therefore, an appropriate temperature and air flow rate are required for drying.
